The next screen can also be used to set, as a percentage, the opening
of the devices connected to analogue outputs Y1, Y2 and Y3.
If the UpCOE is connected in the CW Dual version Coil, the setting of
analogue output Y1 will also be displayed.
When activating one or more components manually, the STATUS
screen will show the
icon.
EEV VALVE SETTINGS
These screens allow the operating parameters of the electronic
expansion valve to be set.
For CW units or those with a mechanical thermostat these screens are
not visible.
MAIN SETTINGS
This screen is used to set:
Valve Type: model of electronic valve used;
Refrigerant: type of refrigerant gas used;
Low SH Protection: activates the LowSH protection which acts
rapidly, closing the valve if there is a level of superheating which is too
low, thus avoiding a liquid return to the compressor;
MOP Protection: activates MOP protection which acts at a normal
speed, closing the value to limit the evaporating temperature if it
reaches an excessive level in order to avoid the compressors shutting
down due to thermal protection.
MOP Set: setpoint for MOP activation
LOP Protection: activates LOP protection which acts quickly, opening
the valve when the evaporating temperature is too low to avoid the
compressors shutting down due to low pressure;
LOP Set: setpoint for LOP activation
